Whirlpool ATR0742SPP0 Limit Switch
This is important due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch has a sensor in the air handler that senses, or governs, if and when the air is warm enough that it can be circulated throughout the house.

- The heating and cooling system refuses to start nor will it stay running longer that five minutes
- The HVAC system starts to go through the startup sequence but stops quickly frequently
